Blind Dual Watermarking Scheme Using Stucki Kernel and SPIHT for Image Self-Recovery

IEEE Access, 2022
In this paper we propose a blind dual watermarking scheme using Set Partitioning in Hierarchical Trees (SPIHT) and Stucki Kernel halftone technique for the tamper detection and image self-recovery.

SAR image denoising method based on sparse representation

The Journal of Engineering, 2019
The coherent nature of radar illumination causes the speckle effect, which gives the synthetic aperture radar (SAR) image its noisy appearance. The probability distribution of speckle noise is multiplicative rather than additive, which makes the ...

Mel-cepstral Methods For Image Feature Extraction [PDF]

, 2010
A feature extraction method based on two-dimensional (2D) mel-cepstrum is introduced. The concept of one-dimensional (1D) mel-cepstrum which is widely used in speech recognition is extended to 2D in this article.
